Okay...I screened the fine particles out of the calcined clay and the gravel grit. I thought it would be a task and a half, but not at all. And have mixed together equal parts of the clay, grit, and orchid bark and potted up one of my year-old adeniums. Overall the tree looks more attractive in the new media. Any suggestions on uses of the fine particles? (I'm letting Rinoa's trees dry one more day.)
